Diabetes is one of the biggest epidemic crises of the 21century. Uncontrolled diabetes is associated with microvascular and macrovascular complications. Tight glycemic control has been linked to a reduction in the development of these complications in both type 1 and type 2 diabetes. The invention of Glucose Meter has changed the diabetes care by enabling patients to monitor their blood glucose level according to their diet, medications and activity. control of glycaemia within the established recommended values is a major therapeutic goal for diabetic patients both in the hospital and outpatient setting. Using of self monitoring of blood glucose 9SMBG0 devices will help diabetic patients detect, prevent or manage of hypo- and hyper …show more content…
There are no single standard criteria to assess the accuracy of a glucose meter so the measurement of accuracy will vary by region and recommendation used for judgment. in the past, five sets of criteria for glucose meter`s performance were used in the accuracy assessment. Criteria which are set by the National Committee for Clinical Laboratory Standards, the American Diabetes Association (ADA) in 1987 and 1996, the U.S. Food and Drug Administration which are according to either the blood glucose level is <50–70 mg/dl. In 2013 new, tighter accuracy standards (ISO: 15197:2013) were drawn up, requiring that 95% of blood glucose results should reach the following standard: Within ± 0.83 mmol/L of laboratory results at concentrations of under 5.6 mmol/L (Within ± 15 mg/dl of laboratory results at concentrations of under 100 mg/dL) and Within ± 20% of laboratory results at concentrations of 5.6 mmol/L (100 mg/dL) or more. The 2014 U.S. Food and Drug Administration (FDA) draft guidance for over-the-counter BGMs requires 95% of results within ±15% and 99% of results within ±20% across the whole glycaemic range.
Clinical accuracy
Clinical accuracy compares the medical decisions based on the test result. It depends on how the result will be used in patient care: for screening, management or diagnosis. For patients and health professionals, it is important to be sure that glucose meter accuracy
When teaching the patient, timing is crucial. I plan about 30 minutes for this teaching lesson because it allows more time for patient to learn new the information. First, I will demonstrate how the machine works and how to apply blood on the test strip while I maintained aseptic technique. Self-monitoring of blood glucose (SMBG) by persons with diabetes is an integral part of intensive glycemic treatment and is widely believed to improve the control of blood glucose levels and health outcomes. For some meter machine, the accuracy can be affected by interfering substances (medication), temperature, hematocrit level, and user technique. In addition, the accuracy of blood glucose meters
Blood glucose needs to be tested to ensure the blood glucose is not too high or too low to determine how much insulin is needed.
In the US, diabetes contributes significantly to excess morbidity and mortality. When uncontrolled, it is a major cause of stroke, heart attacks, chronic kidney disease, diabetic retinopathy, neuropathy, and is the major cause of non-traumatic amputations. It is also increases the risk of death two-fold compared to someone without diabetes . However, among those patients with better control, a reduction in hemoglobin A1C has been shown to decrease the risk of kidney disease , progression of CHF , and an overall decrease in microvascular complications . There is a definite benefit of close blood glucose monitoring and control. In type 2 diabetes, characterized by insulin resistance, the standard of care for mild-moderate disease is oral agents, with transition to subcutaneous insulin as the disease progresses. In type 1 diabetes, characterized by lack of insulin, the treatment depends on either an insulin pump or subcutaneous insulin therapy. Unfortunately, in those patients with insulin dependent diabetes, compliance with finger stick glucose measurements is poor, making insulin administration dependent on those measurements imprecise . One solution to this problem that has been proposed is continuous glucose monitoring (CGM). This system consists of a subcutaneously implanted glucose sensor that wirelessly transmits data to a recorder worn on the body. This allows for frequent (generally a few times an
Self-monitoring of blood glucose (SMBG) NICE NG28 Type 2 Diabetes in Adult: Management7 recommends that we refer to the DVLA “At a glance guide to the current medical standards of fitness to drive” when offering SMBG to those with T2DM We should be routinely offering SMBG to those with T2DM if: •
This test indicates to the doctor whether or not the body is processing glucose correctly. Diabetes is diagnosed with this test if after two hours the blood glucose level is greater than or equal to 200 mg. There is also a Random Plasma Glucose Test, which is a blood test that can be done at any point in the day when experiencing diabetic symptoms (American Diabetes Association, 2013).
Results: According to Table 7.1 for the non-diabetic blood glucose sample measured in tube one .012, tube two .138, tube three 38, tube four .15 and tube five .06. For the diabetic blood glucose sample measured in tube one .16, tube two .71, tube three 1.5, tube four 1.05 and tube five .69.
Managing blood glucose (BG) level in diabetic patients proves to be a challenging goal to insulin. The stand-alone method in many adult acute setting is the use of sliding scale insulin (SSI) to treat hyperglycemia. The goal within these settings is to maintain the BG level below 180 mg/dl (Trotter, Conaway & Burns, 2008).
Blood sugar can be obtained from a drop of blood with a glucometer such as One Touch, or it may be obtained along with the serum chemistry and electrolyte analyses from the lab. A glucometer is a quick and easy way of determining the blood glucose level. Mrs. Baker is a diabetic, and is on an antidiabetic drug, Metformin. Her change in mental status could be due to low blood sugar. This would be easily diagnosed with a glucometer, and easily treated with IV glucose, so it should be one of the first assessments made. A glucometer has the benefit of being a quicker and easier way to obtain a blood sugar level, while a serum glucose may be more accurate at extremely high or low levels.
An hour after the patient consumed glucose, their results climax to 1.5 absorbance showing their body has consumed it all, but has not been able to process it completely. Right after the results climax, the blood glucose levels begin to decrease and return back to normal. It is not safe for this process to take this long because the more glucose that is in the patient’s body for a long period of time, the more likely the patient is to suffer from damaged blood vessels, organs, and many other complications.
If this test was carried out on an individual with type 2 diabetes their GTT results before the test would be more than 7 mmol/L and more than 11 mmol/L 2 hours after the test had started. (http://www.nhs.uk/Conditions/Diabetes-type2/Pages/Diagnosis.aspx, 23/9/2015).
A glucometer is device that is used by diabetics to check their blood sugar. These devices are used by a drop of blood placed on a test strip and the monitor reads it. The finger tip is pricked and the blood
In a hospital setting a CGM be a great resource for caring for a diabetic. Imagine if a nurse had four type one patients to care for in the same shift. This would be a daunting task. A nurse could monitor the patients from 20 feet away from the patient. Changes in insulin dosages could be made more easily, and a sleeping patient wouldn’t be disturbed for a glucose reading. This would be a priceless tool in the hands of a Nurse caring for a Type one diabetic. All Type one Diabetics should be given a CGM covered at no cost thru their insurance upon diagnosis to help nurses provide them with the best possible care.
The primary outcome that will be studied is the blood glucose levels in patients. Blood glucose tests measure the amount of sugar in a sample of blood and is the main tool to check for diabetes control. This will be analyzed in two ways. The first one will be fasting blood glucose levels that patients recall for the previous weeks and that will be informed to the doctor during their appointment. This information will be obtained during the follow-up visits to the doctor that will happen every 3 months for 12 months. The other way it will be analyzed is through the Hemoglobin A1c blood test for a blood sample provided during the doctor’s appointment, which will also occur during the baseline visit and the four 3-month follow-up
CGM is a debatable topic in the patients where tight glycemic control (TGC) regimens are required. There are few studies available supporting the use of CGM for glucose monitoring in case of inpatients. However data from these studies are not consistent. Nurses should also skilled
The program used objective measurements such as OGTT (from capillary plasma), and a majority of the diabetes diagnoses were confirmed according to WHO recommendations. Hence, objective measurements supported the subjective methods of determining the presence or absence of disease which included self-report of diabetes or self-report of diabetes medication, therefore researchers properly captured incident cases of diabetes.
